Vehicle Memory,
Key Memory
How the system functions
You have probably frequently wished that
you could configure individual functions of
your vehicle to reflect your own personal
requirements. In engineering your vehicle,
BMW has incorporated a number of
options for personal adjustment that can be
programmed into your vehicle at your BMW
center.
Vehicle Memory refers to vehicle-oriented
settings and Key Memory refers to person-
oriented settings. You can have up to four
different basic settings adjusted for four
different persons. The only requirement is

Transporting children safely

Passenger airbags lamp
The system checks that the airbag system
is functioning properly when the ignition
key is turned, and the indicator lamp in the
central console lights up for several sec-
onds.
>The indicator lamp lights up continu-
ously when the passenger airbags are
deactivated
>If the passenger airbags are activated, it
goes out after several seconds.
At all times, occupants should sit
comfortably upright and be properly
restrained, infants and small children in
appropriate child-restraint systems; larger
children and adults using the safety belts.
Please note that the word Airbag imprinted
on the door trim panel indicates the air-
bag's location.<
Seat position for children
This is the correct way a larger child no
longer using a child-restraint system
should sit wearing the safety belt, when the
airbag system is activated.
Installing child-restraint
systems
Before installing any child-restraint system
or child seat, read the following:
Never install a rear-facing child-
restraint system in the passenger seat
of this vehicle, unless the passenger air-
bags have been turned off and the indicator
lamp in the center console indicates that
the passenger airbags are deactivated. For
a child, not an infant, certain precautions
should be taken. Position the passenger
seat as far back as possible and at the low-
est level. This important precaution is
intended to maximize the distance
between the airbags and the child. Younger
children should be secured in an appropri-
ate forward-facing child-restraint system
that has first been properly secured. Older
children should be tightly secured with a
safety belt, sitting with their back against
the vehicle seat back. Always ensure that
all occupants, of all ages, remain properly
and securely restrained at all times.<
Always follow the manufacturer's
instructions concerning installation
and use; otherwise the system's protective
function could be impaired. After an acci-
dent, have all parts of the affected safety
belt system inspected and/or replaced by
your BMW center.<
Commercially-available child-restraint sys-
tems are designed to be secured with a lap
belt or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint systems
can increase the risk of injury to children.
Always read and follow the instructions that
come with the system.

Ignition lock
0 Steering locked
This is the only position in which the igni-
tion key can be inserted or removed.
After removing the key, turn the steering
wheel slightly to the left or right until the
lock engages.
If the key is not removed, an acoustic signal
sounds when the driver's door is opened.
Vehicles with automatic transmission:
do not move the selector lever from
position P until the engine is running.<
Interlock
In order to turn the key back to position 0 or
to remove it, move the selector level into
position P first.
1 Steering unlocked
You will find that it is often easier to turn the
ignition key from position 0 to 1 if you move
the steering wheel slightly to help disen-
gage the detent.
Individual electrical equipment and acces-
sories are available for use.
2 Ignition switched on
All systems are operational.
3 Engine started
Engine
Do not allow the engine to warm up while
the vehicle is stationary. Instead, begin
driving immediately at a moderate engine
speed.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and should
decrease as the engine warms up. If engine
speed does not decrease, service is
required.
To prevent the battery from discharging,
always deactivate electrical devices that
are not in use. Switch the ignition off when
the vehicle is not being driven.
Do not allow the engine to run in
enclosed spaces. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas. Breathing
the exhaust gases poses an extreme health
risk, and can lead to unconsciousness and
death.
Do not leave the vehicle unattended with
the engine running. An unattended vehicle
with a running engine poses a safety haz-
ard.
When driving, standing at idle and parking
the vehicle, take care to avoid contact
between the hot exhaust system and flam-
mable materials, e.g. hay, leaves, grass,
etc. Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
Starting the engine
Do not press the accelerator pedal while
starting the engine.
Vehicles with manual transmission:
Step on the clutch when starting the
vehicle. A lockout prevents the engine from
starting if the clutch is not depressed.<
Do not actuate the starter for too
short a time, but do not actuate it for
more than approx. 20 seconds. Release

Parking brake
The parking brake is designed primarily to
prevent the vehicle from rolling when
parked. It operates against the rear wheels.
Indicator lamp
The indicator lamp lights up when
the parking brake is engaged; if you
start driving, an acoustic signal is
heard as well.
The indicator lamp for Canadian
models lights up when the parking
brake is engaged; if you start driv-
ing, an acoustic signal is heard as well.
To engage
The detent engages automatically and the
indicator lamp in the instrument cluster
comes on when the ignition key is in posi-
tion 2.
To release
Pull up slightly on the lever, press the but-
ton and lower the lever.
If, in exceptional circumstances, it
should be necessary to engage the
parking brake while the vehicle is in motion,
do not pull it with excessive pressure. Keep
the release button on the parking brake
lever pressed down while pulling up the
lever.
Excessive pressure can lead to overbraking
and loss of traction, fishtailing, at the rear
axle.
The brake lamps do not come on when the
parking brake is engaged.<
Vehicles with manual transmission:
Always engage the parking brake when parking on slopes and inclined sur-
faces, since shifting into 1st gear or reverse
may not provide adequate resistance to
rolling. Vehicles with automatic transmis-
sion: place the selector lever in
position P.<
To avoid corrosion and one-sided
braking, apply the parking brake
lightly from time to time when coasting to a
standstill – at a traffic signal, for example –
provided that it is safe to do so.<
Manual transmission
6-gear transmission*
When shifting into 5th or 6th gear, it is
important to press the gear shift lever to the
right to avoid accidentally engaging 3rd or
4th gear.
Reverse
Select reverse only when the vehicle is sta-
tionary. Press the gearshift lever to the left
to overcome the resistance.
As you do this, the backup lamps will turn
on automatically when the ignition key is in
position 2.
Do not hold the vehicle in place on
slopes by slipping or riding the clutch.
Use the parking brake instead, otherwise,
the ensuing friction to the clutch plates will
cause a great deal of wear and tear on the
clutch.<

Driving
40 direction, the transmission shifts up. When
the lever is tapped in the – direction, the
transmission shifts down. M1 to M 5 appear
in the gear indicator.
The Adaptive Transmission Control ATC
executes upshifts or downshifts only when
the new gear will provide a suitable combi-
nation of engine and road speed, e.g. ATC
will not execute downshifts if the engine
speed is too high. The desired gear will
appear briefly in the instrument cluster, fol-
lowed by the actual gear.
If you are driving in the manual mode
and wish to accelerate rapidly, e.g. to
pass another vehicle, shift down manually
or with the kickdown function.<
Shifting from M/S to selector lever posi-
tions P, R and N is possible only by going
through position D.
Available indicators
P R N D SD M1 M2 M3 M4 M5
Malfunction
If the indicator lamp comes on,
there is a malfunction in the trans-
mission system.
All of the selector lever positions can con-
tinue to be engaged; in the forward drive
positions, however, the vehicle will be
operating in the fourth gear only.
If this happens, avoid extreme engine loads
and consult the nearest BMW center.
Never work in the engine compart-
ment when a drive gear – forward or
reverse – is engaged. If you do so, the vehi-
cle could move. information beginning on page 94.
Sequential manual gearbox
SMG*
The concept
The sequential manual gearbox SMG is an
automated manual gearbox with which
clutching and shifting is assumed by an
electro-hydraulic system.
The SMG is operated via two shift paddles
on the steering wheel and the selector lever
in the center console.
It offers the following functions:
>Sequential mode: manual mode
>Drive mode: automated mode
>Ability to choose between two different
driving programs: Standard, Sport,
refer to Dynamic Driving Control
>Operating safety through protection
against misshifting
>Automatic upshifts and downshifts in
the drive mode
>Automatic downshifts at minimum
engine rpm
>Kickdown function in the drive mode
>Acceleration assistant.
Selector lever positions
The current selector lever position is shown
by a light-emitting diode on the center con-
sole.
R: Reverse
N: Neutral

Driving
42 You accelerate from higher gears, e.g. dur-
ing passing, by downshifting manually.
In the following situations, the SMG in the
sequential mode assists you:
>The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed cannot be
executed
>During a stop the gearbox is automati-
cally downshifted into first gear
>Shortly before a gear-dependent mini-
mum speed is reached, the gearbox
shifts down automatically without you
taking any action.
Display in the instrument cluster

The currently engaged gear, the selected
mode, and any possible malfunctions are
displayed in the instrument cluster.
Malfunctions
Indicator lamp
If the indicator lamp comes on,
there is a malfunction in the trans-
mission system.
All of the selector lever positions can con-
tinue to be engaged; however, in the for-
ward drive positions the range of available
gears is restricted.
If this happens, avoid extreme engine loads
and consult the nearest BMW center.
Warning tone
An acoustic signal sounds if the SMG gear-
box overheats; if possible you should either
stop or increase your pullaway speed so
that the system can cool down.
For jump-starting and towing, refer to the
information on page 94.
Driving Dynamic Control
The Driving Dynamic Control feature lets
you select between a standard and a sport
program.
Sport program
>The engine responds more spontane-
ously to any motion of the accelerator
pedal
>The vehicle is steered more directly and
traction is enhanced
Additionally with SMG and automatic
transmission:
>The shifting times are reduced
>The engine speed range is optimally uti-
lized in the drive mode.
Activating the Sport program
In ignition key position 2
Press the SPORT button.
The LED in the button lights up.
With automatic transmission:
The sport program of the automatic
transmission is enabled by activating the
Driving Dynamic Control system. Thus, the
selector lever does not have to be shifted
from D to M/S; refer also to page 39.<

44 5Rotary dial for control of the wipe inter-
val or the sensitivity of the rain sensor
Intermittent operation
Not on vehicles with rain sensor.
You can set the wipe interval over four
stages with rotary dial 5.
In addition, the wipe interval is varied auto-
matically depending on road speed.
Rain sensor
The rain sensor is positioned on the wind-
shield, directly behind the interior rearview
mirror.
To activate the rain sensor:
>With the ignition key in position 1 or
higher, move the lever to position 1. The
wipers travel once across the wind-
shield, regardless of the weather.
You can leave the lever permanently in
position 1, it is then only necessary to acti-
vate the rain sensor. To do this
>turn rotary dial 5 briefly.
To adjust the sensitivity of the rain sensor:
turn rotary dial 5.
To deactivate the rain sensor:
return lever to position 0.
Turn the rain sensor off in automatic
car washes. Failure to do so could
result in damage caused by undesired
wiper activation.<
Normal wiper speed
When the vehicle is stationary, the wipers
automatically switch to intermittent wipe,
not on vehicles with rain sensor.
Fast wiper speed
When the vehicle is stationary, the wipers
operate at normal speed, not on vehicles
with rain sensor.

1Cleaning windshield and headlamps
*
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield, otherwise vision could be
obscured. For this reason, use an anti-
freeze agent. Refer to page 83.
Do not use the washers when the reservoir
is empty. Otherwise damage to the washer
pump could result.<
Cleaning the windshield
The system sprays washer fluid against the
windshield and activates the wipers for a
brief period.
Cleaning the headlamps
When the vehicle's lighting system is
switched on, the headlamps are cleaned at
reasonable intervals.
Windshield washer nozzles
The windshield washer nozzles are heated
automatically
* in ignition position 2.

Lamps
Parking lamps/Low beams
Parking lamps
The front, rear and side vehicle
lighting is switched on. You can use
the parking lamps to signal the
position of the vehicle when it is parked.
For information on lighting on one side of
the vehicle for parking, which is available
as an additional feature, refer to page 47.
Low beams
When you switch off the ignition
with the low beam headlamps on,
only the parking lamps will remain
on.
Defective bulbs
The indicator lamp lights up:
At least one bulb of the vehicle's
exterior lighting has failed.
For replacing bulbs refer to page 88.
Follow me home lamps
When you activate the headlamp flasher
after parking the vehicle and switching off
the lights, the low beams will come on for a
brief period.
You can also have this function acti-
vated/deactivated if you wish.<
LIGHTS ON warning
Whenever you open the driver's door after
having turned the ignition key to position 0,
you will hear an acoustic signal for a few seconds to remind you that the lamps have
not been switched off
.
Daytime driving lamps*
If you desire, the light switch can be left in
the second position:
When the ignition is switched off, the exter-
nal lighting is also switched off.
You can have the activation settings
for the daytime driving lamps pro-
grammed on your vehicle.<
Automatic headlamp control*
When the switch is set to this posi-
tion, the system automatically acti-
vates and cancels the low beams in
response to changes in ambient light, for
example in tunnels, at dusk, and when it is
raining or snowing.
The vehicle's external lights remain
on constantly when you switch on the
front fog lamps after the headlamps have
come on automatically.<
Automatic headlamp control cannot
serve as a substitute for the driver's
judgement in determining when the vehicle
lights should be switched on. For example,
the sensors are not able to detect fog. To
avoid safety risks, you should respond to
these kinds of low-visibility situations by
switching the headlamps on manually.<
You can have the sensitivity of your
vehicle's automatic headlamp control
adjusted.<
